According to the vigor of the pendants' vibrations, Wu Yu carefully searched the area.

Very soon, he discovered that there was only a very small zone which would trigger the vibrations. It was a sphere of about 10 zhang in diameter.

There was nothing remarkable about this space. It looked very ordinary, and there was nothing inside it at all. Wu Yu and Wu Jun could move freely within this space, meeting no impediment.

No matter how you looked at it, there was nothing special about this space at all. Except for the fact that it made the "bronze gates" pendants vibrate furiously.

And the moment he left the spherical space, the pendants would fall silent.

Wu Yu was completely stumped.

"What's up with this space? Seems empty enough, but it triggers such a strong reaction from the bronze gates?"

Wu Jun too was puzzled, and constantly checking for any immortal designs or triggers.

A bounty had been placed on both throughout the Demon Immortal Realm now, and it was dangerous for them to linger in any place for a long time.

But they had found this lead with great difficulty, and could not just pass it up so easily. They had a hunch that this was no trap by the demonic emperors. Which meant that this 10 zhang spherical space could well hide some ancient secret.

The two continued to search the space for any clues, looking out for any mechanisms or immortal designs. They found nothing.

They did not give up, but abided for another five years.

Within this time, Wu Yu had nuked every inch of the sphere. He had used Submerged Cloud Seal to tear at it, and turned it into all but void. There should be nothing there.

Even so, the space did not change at all. Only the bronze gates-turned-pendants continued to react as strongly as ever.

Although lingering might invite danger, but they were unwilling to give up.

After all, such an intense reaction probably indicated a huge eternal demon emperor corpse.

Before, the nine heads of the Apocalyptic Demon Emperor had allowed Wu Yu to improve greatly, and this was more than a hundred times stronger. This eternal demon emperor corpse must be incredible in either quantity or quality.

If he could just get his hands on it, Wu Yu would not only be able to rocket upwards, but Wu Jun might even find a breakthrough to the eternal immortal emperor realm.

Therefore, they could not bring themselves to leave.

However, they had truly overstayed. Wu Yu's gut sensed danger, and Wu Jun's brows flew up in surprise. Something was coming.

The moment they reacted, the space around them began to crumble, with five strong auras appearing around them!

"It's the demonic emperors!"

Both sprang into action!

The five demonic emperors had actually stealthily crept up on them and attacked with a barrage of heavenly rules and techniques.

"Worldly Illuminator heavenly rule!"

Wu Jun immediately activated his power, creating a milky-white barrier of immortal qi that shielded him and Wu Yu within!

They were up against five. The odds were not good.

If it were one on one, Wu Jun could hold him for a long time, and defeating him was also a possibility. But now, his Worldly Illuminator heavenly rule looked frail, beginning to shudder after just a few moments.

Of course, these few moments was more than enough time bought for Wu Yu. He took Wu Jun into the Floating Dreams Pagoda, and then somersaulted away.

Even with five demonic emperors barring the way, they were not barring the ways that Wu Yu used.

Again, they were unable to hold Wu Yu, and he made good his escape.

"It's the Fathomless Starry Sea. He was spying on us, and quietly let them know!" Wu Jun thought back.

"A sly one indeed." Wu Yu was not pleased. After Fathomless Starry Sea had been detected by Wu Jun previously, he now kept a safe enough distance that they could not sense him.

Until the five demonic emperors showed up.

"But that place is unusual indeed, for the bronze gates to react thus. Let's stick around and watch." Wu Yu said. Their next step would depend on Full Moon of Nanshan.

His Gone from the Skies would elude even the demonic emperors.

Wu Yu was burning with curiosity regarding the sphere. and Full Moon of Nanshan immediately complied with the plan.

As Full Moon of Nanshan returned, only a few breaths' of time had passed. The five demonic emperors were clearly beside themselves with anger. Again, they had lost all track of Wu Yu.

However, Full Moon of Nanshan saw that the various heavenly rules and techniques that the five demonic emperors used had fused after Wu Jun's Worldly Illuminator heavenly rule dissipated. They came together within the sphere.

As their attacks landed on the sphere, the five different elemental heavenly rules reacted.

It was a great coincidence that the five demonic emperors mastered the five affinities. A change was triggered within the space!

To the surprise and delight of the five demonic emperors, a massive and ancient pair of bronze gates appeared out of thin air. These bronze gates were even bigger than the true forms of Olden Golden Mountain or Unending Crepuscular Sea. They appeared in the air, an immovable entity that struck awe in the kings.

Full Moon of Nanshan was watching secretly. He saw that these bronze gates were an enlarged version of the mini bronze gates that Wu Yu held. On the bronze gates, large words declared: "The Eternal Emperor Tomb. No Living Being Allowed!"

These words stung at Full Moon of Nanshan's eyes. As though there was some sort of compulsion on them that prohibited him from entering.

"Eternal Emperor Tomb? What is that?"

Full Moon of Nanshan was amazed, and immediately sent an immortal message talisman to Wu Yu.

Wu Yu too was overjoyed to hear this. That place must hide many secrets, and perhaps the secret of the bronze gate pendants he held would also be revealed within.

The little bronze gate pendants that Wu Yu held were definitely closely tied to these huge ones that barred the Eternal Emperor Tomb. No wonder they reacted so strongly.

"So the gates required a combination of the Five Affinities' powers.

Olden Golden Mountain was Metal.

Unending Crepuscular Sea was Water.

Perpetual World Tree was Wood.

Dignified Lava Beast was Fire.

Celestial Meteor was Earth.

It was fortuitous that they could unlock the bronze gates.

It was the pendants that had allowed Wu Yu to find this place. It was like a grain of sand within the gigantic desert that was the Demon Immortal Realm. It was well-hidden by a creator who did not wish it found.

A plethora of secrets must await within.

But now the demonic emperors were occupying the entrance. Wu Yu could not get near. He could only hold his nerve and see what their next move was.

The appearance of the bronze gates had shaken the demonic emperors up.

After all this time in the Demon Immortal Realm, they thought that there were no more secrets in the Demon Immortal Realm hidden from them. And now these bronze gates had appeared - and they had never heard of the Eternal Emperor Tomb before!

"Seems to be the place where the eternal demon emperors are laid to rest?" Unending Demonic Emperor spoke first in a voice that trembled, belying his excitement.

"Once we open the Eternal Emperor Tomb, we will all be eternal demon emperors in a flash." Olden Demonic Emperor said greedily, his metallic voice turning tinny.

The other three demonic emperors did not comment, but they were equally worked up.

"To think that the kid was actually on to the Eternal Emperor Tomb. Let's try and open it." Celestial Meteor said sharply.

The warning on the bronze gates was completely ignored by the five demonic emperors.

"No Living Being Allowed" struck fear into their hearts, an inexpressible and humbling fear that seemed to come from a higher source, but their ambitions overcame that fear.

"Come, let us join forces and blast open the tomb doors!"

At the behest of the Perpetual World Tree, the five demonic emperors attacked together, sending their incredible heavenly rule power towards the bronze gates!

From a distance, Full Moon of Nanshan watched. He was wondering - if they managed to open the doors, should he go in?

A decision best left to Wu Yu!

Full Moon of Nanshan had full confidence in him. Wu Yu's decisions had never led them astray before, and so he could not be bothered to think for himself. Why not spend the thinking time sleeping instead? Bank some energy in case he met a beauty......

However, this wondering did not even matter.

Despite being battered by the demonic emperors' attacks, the bronze gates did not move an inch, and remained completely pristine. They could not even leave a mark.

The demonic emperors did not lose heart, but continued to cycle through their entire arsenal of attacks. The bronze gates remained untouched.

"Er......"

The demonic emperors were stumped. What in the world were these bronze gates made of, to be able to withstand such attacks?

But they were hopping with anticipation. Behind these doors must lie incredible mysteries.

They strained themselves fully but were unable to open it. And the more they failed, the more their interest began to build.
